String Instruments : String Instrument Bows


In this clip, we’ll learn about bows. The
bow is made up of the frog, which is right here, and the hair and then the frame of the
bow, which is made out either wood, fiberglass or carbon fiber, depending on what level,
you know, what level bow it is. Most commonly, for higher end bows, they are made out of
wood and they can get very expensive, into the ten, twenty, thirty thousand dollar range
or higher. Carbon fiber is usually mid to high range. They do make some carbon fiber
bows that are a little bit cheaper and stuff. But, they’re pretty nice, I mean they’re basically
indestructible. And they make carbon fiber cellos too. And those are basically indestructible
too, which is nice because cello, cellos and violins and all the stringed instruments really
are fragile in a lot of situations and where you need to take them and stuff. So, fiberglass
bows are usually for beginners and sometimes they can, they can have nice fiberglass bows,
but most of the time they’re beginner bows. The second part is usually made of horsehair,
and you use something called rosin, which is, it comes from pine trees mainly, and that
what actually creates the friction of the bow between the string, because without rosin,
the horsehair would just slide across the string and you would not get any friction.
So, rosin is, obviously, very important and it can come in different grades of darkness
to lightness. The darker the rosin, the more friction it’s going to create on your string.
And you can see there’s rosin on my bow, because it’s a cloud if, you know, a good amount of
rosin on your bow is important to get a good sound. And then the last part of the bow is
the, the thing, the peg that actually tightens the bow. So when you store your bow, it’s
very loose and when you tighten it up, you need just the perfect amount of tightness
to get the perfect sound out of a stringed instrument.
